Effects of Bihemispheric Transcranial Direct Current Stimulation on Motor Function in Stroke Patients

A constant current stimulator (ZMI Electronics LTD.,Taiwan,2012) will be used through 2 saline-soaked surface gel-sponge electrodes (22 cm2 active area). Real stimulation consisting of thirty minutes of 2 mA direct current with the anode placed over the ipsilesional and the cathode over the contralesional motor cortex (C3 and C4 of the international 10-20 EEG electrode system).

For sham tDCS, the same electrode positions were used. The current was ramped up to 2 mA and slowly decreased over 30 seconds to ensure the typical initial tingling sensation
